The area of the modern city of Ibaraki was within ancient Settsu Province, and was the site of large settlements in the Yayoi period and was the location of large burial mounds in the Kofun period, including the Ota Chausuyama Kofun, which is designated by the Imperial Household Agency as the mausoleum of Emperor Keitai. In the first half of the Muromachi period, Kusunoki Masashige built Ibaraki Castle, and the jōkamachi which was established around this castle became the core of the modern city. In the Sengoku period, the area was ruled by the Christian daimyō, Takayama Ukon. In the Edo Period, it was directly controlled by Tokugawa shogunate due to its strategic importance on the Sanyōdō highway.
